Detailed Reviews

What to Look For 0 Drill Bit Size

Bit Diameter Range

The smallest to largest hole size the set can produce (e.g., 0.30 mm‑1.60 mm). Determines which precise openings you can drill.

Material & Hardness

Usually high‑speed steel (HSS) with heat‑treated alloying. Affects wear resistance, edge retention, and ability to drill hard materials without breaking.

Shank Size & Type

Diameter and shape of the bit’s shank (e.g., 0.20 mm‑0.45 mm round). Must match the chuck of precision drills to ensure a secure grip and accurate alignment.

Set Quantity

Total number of bits included (e.g., 40 pieces). Larger sets provide more size options and better value for frequent DIY or professional use.

Maximum RPM Rating

Highest safe rotational speed the bits can handle (often up to 10,000 RPM). Influences drilling efficiency and prevents overheating or premature wear.

Material Compatibility

Types of substrates the bits can effectively drill (wood, stainless steel, aluminum, plastics). Guides buyers on whether the set meets their specific project needs.

Buying Guide

Key Features to Consider

A #0 drill bit measures approximately 0.060 inches (1.52 mm) in diameter, making it ideal for precision work such as jewelry, electronics, and fine woodworking. Look for high‑speed steel (HSS) or cobalt alloy for durability, and consider titanium or black oxide coatings to reduce heat buildup and extend tool life. A straight shank fits most standard chuck sizes, while a reduced‑length shank improves rigidity in compact drills. Tolerance and runout specifications are critical; low runout ensures accurate, clean holes.

Budget Recommendations

Entry‑level #0 bits can be found for $2‑$5 per piece in bulk packs, suitable for hobbyists who need occasional use. Mid‑range options range from $8‑$12 for a single premium‑coated bit, offering better wear resistance and tighter tolerances for professionals. High‑end bits, often sold in sets of 5‑10, cost $30‑$50 and feature cobalt or carbide construction with precision grinding, delivering maximum lifespan for intensive production environments.

Common Pitfalls to Avoid

Avoid using a #0 bit on materials beyond its strength rating, such as hardened steel, which can cause premature breakage. Do not overtighten the bit in the chuck; excess pressure introduces wobble and reduces accuracy. Skipping proper lubrication or using low‑quality coatings can lead to rapid dulling and heat buildup, resulting in poor hole quality and shortened tool life.

Frequently Asked Questions

What does a "0" drill bit size mean?

"0" (zero) is a standard drill bit size in the American Wire Gauge (AWG) and fractional inch systems. It corresponds to a drill bit with a diameter of 0.0600 inches (1.524 mm).

How does a 0 drill bit compare to other common sizes?

A 0 drill bit is slightly larger than a #1 drill bit (0.2280 inches) and smaller than a #00 (0.0700 inches). In metric terms, it falls between 1.5 mm (approximately 0.0591 in) and 1.6 mm (0.0629 in).

What applications typically use a 0 drill bit?

A 0 drill bit is commonly used for drilling small holes in electronics (e.g., mounting hardware for circuit boards), jewelry making, model building, and creating pilot holes for #6 to #8 screws in wood or plastic.

Can I substitute a 0 drill bit with a metric size?

Yes. The nearest metric equivalent is a 1.5 mm drill bit (0.0591 in). While 1.5 mm is slightly smaller (by 0.0009 in), it is generally acceptable for most non‑critical applications. For tighter tolerances, a 1.6 mm bit (0.0629 in) may be used, but it will be marginally larger.

How do I maintain a 0 drill bit for optimal performance?

Keep the bit clean and free of debris, lubricate with cutting oil when drilling metal, and sharpen it regularly using a fine‑grit diamond or carbide sharpening stone. Store bits in a protective case to prevent nicking the cutting edges.
